File transfer management system and method

technical field

The invention is a data management technology, especially a file transmission management system and method.

Background technique

The network allows users to share the resources of the local system with other network users, and to access information from centralized or remote systems. The Internet, in general, is used to provide large-scale data exchange between computers and networks. The Internet provides fast access operations for countless client computers and hundreds of servers (providing hypertext transfer protocol HTTP, file transfer protocol FTP and e-mail services). However, when transmitting large amounts of data over the Internet, it takes more time and there are security concerns.

The client computer is connected to the portal server through the Internet. The entry server is connected to the file server through a dedicated line. The portal server may obtain a first transfer time measure representing the time required to transfer between the portal server and the file server via the Internet, and obtain a second measurement representing the time required to transfer between the portal server and the file server via the dedicated line. a transit time metric, and determining whether the second transit time metric is better than the first transit time metric. If the second transmission time measurement value is better than the first transmission time measurement value, execute the file transmission operation between the client computer and the file server through a dedicated line. The portal server can further perform a file transfer operation between the client computer and the file server through the Internet or send a message to suggest that the client computer perform the operation through the Internet when the second transfer time measurement value is worse than the first transfer time measurement value. file transfer.

The file transfer management system of the present invention further includes a proxy server, which is connected to the entrance server through a firewall, and connected to the file server through a dedicated line. The portal server can send a file transfer request with a file ID to the proxy server. The proxy server can intercept the file transfer request to determine whether a cached file corresponding to the file identification code exists. If it exists, it will respond to the cached file to the entry server. If it does not exist, it will forward the file transfer request to the file server to obtain the corresponding A specific file based on the file ID.

Detailed ways

FIG. 1 is a network environment architecture diagram showing a data transmission management system 20 according to an embodiment of the present invention. System 20 comprises a client computer 21, an Internet Service Provider (Internet Service Provider, ISP) server 22, a portal server (portal server) 24, a proxy server 25, a firewall (firewall) 33, a Department file server 23 and routers 31 and 32. The client computer 21, the ISP server 22, the portal server 24, the proxy server 25, the firewall 33 and the router 31 are all located in Japan, and the router 32 and the file server 23 are located in Taiwan Province of China. When the client computer 21 is equipped with a modem or an asynchronous digital subscriber line (ADSL) modem with required software, the ISP server 22 provides its data access service on the Internet. The client computer 21 can pass through the Internet provider server 22 and the Internet 30, and the file server 23 can transmit and receive huge files exceeding the size of one gigabyte. However, due to the bandwidth of the Internet and complex network routing procedures (network routing procedures) ), the file transfer takes a lot of time.

The client computer 21 can access the portal server 24 through a virtual private network tunnel (Virtual Private Network Tunnel, VPN Tunnel), which is constructed using a public cable and connected to the portal server 24. The channel uses encrypted transmission and other security devices to ensure that only authorized users can access information on the Internet, and the data will not be intercepted. The firewall 33 is designed to prevent unauthorized access to information in the private network and can be implemented in software, hardware or a combination of both. It is mostly used to prevent unauthorized users from entering private networks, especially intranets, via the Internet. All internal information entering or leaving the enterprise must go through the firewall, which inspects every piece of information and blocks information that does not meet certain security standards. According to the appropriate transmission time measurement value of the Internet 30 and the leased line 34, such as the round-trip time (Round-Trip-Times, RTTs) value, the portal server 24 selectively transmits the file server 23 through the Internet 30 or the leased line (leased line) 34 access. The proxy server 25 is connected to the router 31 and executes information/file transfer operations between the portal server 24 and the file server 23 . The proxy server 25 intercepts all requests sent to the file server 23 to determine whether the cache file corresponding to the file identification code in the request exists, and if it exists, then responds to the cache file, if it does not exist, then forwards the file with the file ID Request to the file server 23 to obtain the corresponding file. The proxy server 25 can greatly improve the efficiency of file transfer, which saves a considerable amount of time for obtaining files. The router 31 and the router 32 are connected in a point-to-point manner through a dedicated line 34 . The dedicated line 34 establishes a permanent call connection between the routers 31 and 32, which is provided by the telecommunications carrier. The leased line 34 is always on and used for business to connect remote offices. Since this connection is only used by one customer, the carrier can ensure a certain quality of communication. For example, the dedicated line 34 provides more than 65 megabits of bandwidth, so that the client computer 21 can receive and transmit huge files from the file server 23 at a faster speed than the Internet 30 for receiving and transmitting operations.

FIG. 3 is a flow chart of a file transfer management method according to an embodiment of the present invention. In step S311, a file transfer request is received. The file transfer request may indicate to receive a specific file from the file server 23 , in another case, the file transfer request may further include a file and instruct to transfer the file to the file server 24 . In step S321, a first transmission time measurement value is obtained, which is preferably a return time value, which represents the time required for transmission between the portal server 24 and the file server 23 via the Internet 30 . In step S323 , the second transmission time measurement value is obtained, which is preferably a return time value, which represents the time required for transmission between the portal server 24 and the file server 23 via the dedicated line 34 . The transit time measurement value can be detected periodically by the ingress server 24, and real-time detection can also be performed. In step S331, it is determined whether the second transit time metric is better than the first transit time metric, if yes, the process proceeds to step S333, if not, proceeds to step S335. In step S333, the file transmission operation is performed through the dedicated line 34. In a preferred situation, the portal server 24 can send a file transfer request with a file identification code to the proxy server 25 . The proxy server 25 can intercept the file transfer request to determine whether a cached file corresponding to the file identification code exists, and if it exists, the cached file will be responded to the entry server 24, and if it does not exist, the file transfer request will be forwarded to the file server 23 . In step S335 , execute the file transfer operation through the Internet 30 , or send a message to the client computer 21 indicating that it can receive and send files from the file server 23 through the Internet 30 .
